Application filed June 24, 1913.

Be it known that we, JOHN S. BARNES and NATHAN E. Si-innwooo, citizensof the United States, residing at Detroit, county of llayne, State ofMichigan, have invented certain new and useful Im rovements in tend-Guides t'or ltopeeM. hing Machines, {J I declare the following to bea full, clear, and exact description of the same, such as will enableothers skilled in the art to which it pertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification. v

My invention relates to rope making; machines and particularly to astrand-guide therefor.

One object of the invention is to provide a strand-guide embodying amongother characteristics a frusto-conical body having where and strandreceiving grooves and a depend ing handle to which a weight is attachedto hold the strand-guide against rotation with means to regulate thetension of the strands in the grooves. I Other objects and advantageswill later appear. In the drawings: Figure 1 is a perspective Viewshowing the strand-guide threaded preparatory to twisting the strandsaround a wire core. Fig. 2 is a perspective view showing several twistedstrands disconnected from the hooks they normally engage when beingtwisted and connected to a central hook to finish the twistingoperation.

Referring now to the letters of refer" ence placed upon thedriawing'sz-A is a frame which may be secured to a suitable support inany suitable manner.

A denotes a hub in which the shaft-B is journaled and which shaft has ahook B, there being an operating crank C secured to the outer endof theshaft whereby it may be manually actuated.

1) indicates a driving gear mounted on the drive shaft B.

(Z denotes a tr 'nsverse pin set in the shaft and lodged i a recessformed inthe hub of the gear D, thereby securing the gear to the shaftand providing against its lateral movement.

E denotes a with the main driving on stub shafts or bolts arms of theframe.

G are hooks preferably formed of sheet metal, having a bifurcated shank,the tines r of which are secured to. the pinions E in any suitablemanner.

H is a strand guide approximately cone shaped, having a plurality ofperiphe..-al grooves it running longitudinally to receive the bindertwine or strand. wires 1, forming the cable and with a central bore itfor the passage of a wire or other core around which the strands maywrapped. Y

is :1 depending handle for manually controlling the device, and H is aweight suspended from the end of the handle, -the object of the latterbeing to prevent the re tation of the strand guide due to the tension ofthe twisting rope should the handle be. released by the operator.

i are adjustable tension hooksin line with the grooves it, through whichthe 7 strands l of the cable I J, J, are a pair of swivel hooks, one ofwhich receives the strands of the cable, the

other being connected with a rope or belt K from which is suspended aweight.

K is a pulley or sheave over which the rope or belt K passes.

The device being secured to a suitable support, binder twine or yarn isthreaded through one of the grooves in the strand guide H, under itsadjustable hook H to one of the several hooks G, thence back through thegrooves h in the strand guide to the swivel hook J,-which is locatedat'a suflicient distance from the twisting device to construct therequired length of rope. The twine is looped back and forth from thehook J through the grooves in the strand guide to the several hooks G,to provide the required number of threads desired for each strand. Thetension on the several threads of eachstrand being regulated by theadjustable hooks H thedevice is then put in operation by manuallyrotating the crank arm C, the maindriying we gear D actuating theseveral pinions thereby twisting the individualthreads of yarn or twineinto strands. The rotation of the gears being continued -theseveralstrands are twisted together beyond the contracted 1" end of thestrandguide, and as the strands are twisted together the'guide is graduallyforced forward by the twisting strands toward the hooks G as will bereadily understood. Upon the strand guide reaching a.

point near to the hooks G, the several strands are removed from thehooks G and are looped over the central'h'ook B of the drive shaft. asindicated in Fig. 2. The end of the cable is then grasped by theoperator to hold it against rotation and the twisting gear is againoperated which serves to twist the strands more tightly together.thereby effecting the completion of the finished rope. If it is desiredto construct a cable having a metallic or other core, the wire or othercore L. is threaded through. the central bore 71 in the strand guide. asindicated in Fig. 1. the threading of the yarn or twine over the hooks Gand the twisting of the threads into strands being effected aspreviously described. l pon the completion of the twisting of the yarninto, strands, the several strands are twisted around the central coreby a further operation of the crank arm as indicated in Fig. 2 of thedrawings. l'pon the strand guide being forced up close to the hooks. thestrands from the hooks (l and looped over the cen tral hook as indicatedin Fig. 1, the cable being completed by grasping the end of the rope.the strands being then twisted close to are disengaged the hook andtightly together in the manner previously described.

Having thus described our invention, what we claim is:-

In a device such as described, a strand guide adapted to be supported bythe strands to be twisted and including a frusto-conical body havingspaced longitudinal guide grooves therein for receiving the strands tobe twisted, and a central longitudinal bore formed therein and"extending therethrough. a depending handle attached to the strandguide. a weight attached to the handle 'for holding the strand guideagainst rotation. and hooks in the end of the strand-guide at the innerends of the longitudinal grooves. the hooks being adjustable -in theinner end of the strand guide for engaging the strands in said groovesan regulating the tension thereof.

In testimony whereof. we sign this specificationin the presence of twowitnesses. J( )l-l BARXES.
